Factual error: During the final fight, Liam Neeson jumps down an aisle to pick up the pistol that is hurled from the floor upwards in the air and shoots the villain in the head. The problem here is with physics. The plane was in radical descent moments before. The pilot eventually brings up the nose. At that moment, the gun and Liam Neeson himself would have been pinned to the floor.

Factual error: Although the exterior and interior of the aircraft in the movie are reasonably accurate, the cockpit does not resemble any real life aircraft, let alone a 767. In actuality, the cockpit looks hilariously unrealistic for numerous reasons. It appears to be a bunch of random panels and pieces of other aircraft and their own designs all stuck together to form something that looks outrageously stupid. They even have a 4-engine throttle in there, even though it is a two engine plane.

Question: In the scenes with the fighter jets flying besides the airliner, the fighters are depicted running with the afterburners (re-heat) on. This surely would not be the case for flying at a low speed of around Mach 0.8?
